EDWARD (J. MEIER, OF PHOENIXVILLE, PENNSYLVANIA.

FURNACE-TILE.

Original application filed August 14, 1915, Serial No. 45,551.

To all whom it may concern Be it known that I, EDWARD C. MEIER, acitizen of the United States, residing at Phoenixville, in the county ofChester and State of Pennsylvania, have invented certain new and usefulImprovements in Furnace-Tiles, of which the following is aspecification. 7

My invention relates to improvements in furnace tile, and moreparticularly to an improved cast iron tile having an inclined groovetherein adapted to direct the steam from a soot blower inserted througha stay tube in the box header into the groove formed in the battlingtile supported on the boiler tube.

In the arrangement of bathing tile on boiler tubes, it frequentlyhappens that such tile are so disposed that a soot blower directedthrough a stay tube will be out of alinement with the upper or groovedface of the tile, and in such case my improved metal tile is used andoperates as a deflector or inclined trough to properly direct the steaminto-the groove of the bathing tile.

A further object is to provide a metal tile which is especially adaptedfor use in connection with my improved grooved bafflin tile, and whichisso arranged that the inclined groove in the metal tile registers withthe groove in the bafliing tile, and insures a proper direction of thesteam for blowing out the soot.

This is a division of my application for patent on furnace tile, filedAugust 14, 1915, and given Serial No. 45,551.

lVith these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a fragmentary view in verticallongitudinal section illustrating my improvements. Fig. 2 is afragmentary view in section on the line 2-2 of Fig.1, my improved metaltile being shown in end elevation. Fig. 3 is an enlarged fragmentaryplan view showing the box header and stay tube in section, and the otherparts in elevation.

with boiler tubes 3, and provided with stay tubes 10.

The construction above described is a common type of boiler, and I wouldhave it understood that my present invention is not limited to anyparticular construction of boiler, and may be used with various types.

On the boiler tubes 3, baiiiing tile 4 are supported, and these bathingtile are preferably of burnt fire brick or clay, and are provided intheir upper faces with longitudinal grooves 5 constituting a repositoryfor soot which accumulates therein. These tile 4 I term baffling tile todistinguish them from my improved metal tile (5, although the latteroperates as a battling tile. This tile 6, as above stated, is preferablyof cast iron, and is provided at its sides with curved faces 7, whichrest against and are supported by the boiler tubes 3. The tile 6inclines upwardly from its outer to its inner end, and is of generaltrough shape throughout, the upper end of the tile 6 registering withthe grooved surface 5 of tile 4, while the lower end of the tile 6 islocated in a plane below the stay tube 10 through which the soot blower(not shown) directs the steam to blow out the soot which is deposited inthe groove 5 of the tile. The stay tube 10 is up-set or flared outwardlyat its ends as shown at 8, and the tile 6 at one end is recessed asshown at to accommodate the end 8 of tube 10 and allow the tile 6 to liesnugly against the header 2.

With my improvements it will be noted that when the blower is directedthrough the tube 10, the steam will be directed through the tile 6 intothe groove 5 of tile 4, and it will also be noted that the tile 6 hasits groove 11 widest at its end adjacent the tube 10 and graduallydecreases in width to its other end where it conforms in width to thewidth of the groove 5, so that the tile 6 not only tapers upwardly fromOne end to the other, but its groove or trough 11 decreases in widthfrom its inlet to its outlet end, hence the steam is more or lessconfined, and the tile operates to a certain extent as a nozzle todirect the steam through the groove 5.

Various slight changes might be made in the general form and arrangementof parts described Without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly full Withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim us new and desire tosecure by Letters Patent is:

1. A tile. con'iprisingr a steam guide adapted .to be located at the endof a Series of battling tile and having :1 groove in its upper faceforming a steam passage widest at its inlet end and diminishing in widthto its outlet end, substantially as described.

2. A tile, comprising at steam uide adapt- In testimony whereof I havesigned my.

name to this specification in the presence of two subscribing Witnesses.1- r '7 EDVARD C. MEIER.
